Hello,
I am trying to simulate temperature increase due to friction in a gearbox. I am performing this analysis in coupled field transient so that i can apply rotation and friction between the gears but the problem is, in the temperature result, minimum values are going in negative values...
Hello All,
I am performing a modal analysis of a shaft in prestressed condition, now the result is that its safe upto 3 modes and after that stress and deflection are high. what is the meaning of these modes in actual working condition of my shaft? How do i know that shaft will reach upto...
@FEA WAY AND @THOMASH, THANK YOU BOTH FOR YOUR RESPONSE. CAN YOU PLEASE SUGGEST SOME TEXT TO UNDERSTAND MODAL ANALYSIS AND ITS USE FOR FURTHER HARMONIC RESPONSE ANALYSIS. I AM WORKING ON A MACHINE ASSEMBLY AND I AM TRYING TO FIND OUT THE VIBRATIONS AND STRESSES DURING THE OPERATIONS USING ANSYS...
@FEA way, Thank you for your reply. I understood it but then how do we interpret the result then, if we don't know the actual values of stress and deflection and then what is the use of modal analysis then? what can we interpret with frequency?
HELLO,
I am performing modal analysis to find natural frequency and their deflection. What does these deflection values at different modes indicates? Also If modal testing is done on a machine constraining the base of the machine. How much deflection is allowed in such case?
I wanted to highlight only one issue in the cold working process i.e. yield stress can be increased substantially compared to UTS in the cold working process. So for equipment design if allowable stress depends on UTS only then why should we do cold working. Is there any other advantage of a...
Cold working is the process of plastic straining below the recrystallization temperature in the plastic region of the stress strain diagram. Properties of the material obtained from hot rolling are quite different from those obtained by cold working.
Consider the stress strain diagram of fig...
I AM GETTING THIS ERROR ON OPENING ONE SOLVED PROJECT FILE. IT WAS SAVED PROPERLY ON LAST EDIT.
PLEASE CAN SOMEONE HELP ME WITH THE ERROR.
SYSTEM.XML.XMLEXCEPTION:'-', HEXADECIMAL VALUE 0X02,IS AN INVALID CHARACTER. LINE 1656, POSITION 261.
PLEASE HELP SOMEONE.IT TOOK MANY DAYS TO FINISH...
Thanks for your reply....
What i understood is, if i am converging stress on one part of the assembly then i can not give local mesh size to that body though i can apply size on surface or curve of that part. I removed local mesh size and the ERROR IN MESH REFINEMENT MODULE Is gone.correct me if...
Hello,
I am doing a simple shaft analysis qith only one step. I am applying convergence of 5%. The result is not getting converged if i apply fixed support. But if i apply displacement support it is converging successesfully. What is the reason??
Pls if anyone can help me with this...
Hello all,
I am trying to do a convergence analysis. But there is an error coming A FAILURE OCCURED INSIDE THE MESH REFINEMENT MODULE. I tried many options but the solutuion does not get converged (i am getting result at the base mesh). What is this error about can anybody help me??
Hello,
I am doing harmonic analysis using MSUP. Here i am applying moment load in harmonic boundry condition but there is no effect of moment in the result. Changes in the value of moment doesnt make any change in the result. My model has a shaft with torque. Pls let me know what is...
Hello,
I am doing a mid surface analysis using shell181 element. I want to use surf 154 element also but i dont know how to use it or how to apply it to my model. Pls help
Is there any way to select the element type of our choice??
Thanks
hello,
I have this cylindrical permanent magnet coupler with conducting sheet between them. outer magnet is rotating the inner one. I want to find out the torque on inner magnet. I don't know how do I apply this boundry condition? pls help
hello all,
I am performing a magnetostatic analysis. It consists of vertical sticks of magnets inside the cylindrical case, there is a air gap between each magnetic stick, I want to apply a voltage difference on two vertical sides of stick but I suppose voltage difference can only be...
Hello,
I am doing magneto static analysis in ansys. it is a cylindrical magnet fitted in steel cylindrical body both are rotating. there is one more magnet inside these two cylindrical parts. the magnetic force is transmitted through air between two magnets and the inner most magnet also...
hi.....
I have this shaft fixed at one end and free at other end. I wanted to see the deflection of free end due to gravity. I am using SI system library for material (N/m2) (E= 2.1 x 10^11 , density= 7833) and applying gravity of 9.8 m/s2. but the deflection and stresses are coming very...
Hello eric,
My profile is a continuous curve and in dwg also it shows a tangent continues spline curve. I have seen that in dwg when i select the curve it shows two differnt curves, one is my profile curve it self and one is the curve connecting the vortex points of the curve. Second thing is...
Yes it persists the same problem......i dont know why but i am not able to extract the exact profile coordinates of the hyperbolic profile. Every time i have to check it by machining and then i come to know that some portion of the profile has got error. Some times the half profile is perfect...
